Hawaiian Mermaid Legends: Myth, Mystery, and the Mermaid Cave

Hawaiian mermaids are part of the islands’ ocean lore—stories passed along through generations of sailors, fishermen, and adventurers who share a deep respect for the sea. In legend, Hawaiian mermaids are said to be curious yet cautious beings, approachable only when their environment is treated with care and reverence.

This post explores Hawaiian mermaids as part of ocean folklore and Hawaiian mythology. Those drawn to mermaid mythology often speak of quiet observation, patience, and understanding the rhythms of the ocean. Sightings, like many ocean encounters, are said to happen when least expected.

Where Mermaid Legends Are Said to Appear

To catch a glimpse of a mermaid, first research their resting and feeding spots and know the ocean currents in the area. The Leeward side of the islands is more predictable and more hospitable hence easier to access and see a mermaid and/or her surroundings. It is wise to attempt viewing during low-tide as mermaids tend to be in and around cavernous and rocky shoreline haunts. Wearing appropriate water footwear is helpful while traversing rocks and stones.

Finding a mermaid gossip or pod, just like finding dolphins or whale watching, is a hit or miss adventure so don’t be too disappointed if there isn’t a mermaid in sight, this might be an opportunity to see Green Sea Turtles or a Hawaiian Monk Seal. Like other marine life, mermaids are amazing swimmers, and move much faster than humans and faster than the shutter-speed of any camera.

Fact or Fiction? The Origins of the Hawaiian Mermaid Legend

For students of history and marine science, who are interested in background on the Hawaiian Mermaid, the origin of the Hawaiian Mermaids dates back to 1837. Identified and documented by a Danish author. The author, along with a scientist and a Hawaiian royal, travelled from island to island investigating the resting habits of the visiting Nereid through firsthand accounts from local fishermen and navigators. The Hawaiian Mermaid is not indigenous to Hawai’i, and not from any of the other Oceania islands. Polynesian navigators have tracked her homeland back to Copenhagen, Denmark.

Respecting Hawaiʻi’s Marine Life

While mermaids belong to legend, Hawaiʻi’s marine wildlife is very real and protected.

When encountering species such as:

• Hawaiian Monk Seals (ʻīlio holo i ka uaua)
• Green Sea Turtles (Honu)

Please keep a safe and respectful distance. Touching or approaching protected species is prohibited and may result in fines. Observing from afar and photographing responsibly helps preserve Hawaiʻi’s ocean life for future generations. Photographs from a distance are a great way to capture and share your adventure. I always ask permission before taking photographs of mermaids.

The Mermaid’s Lair: A Leeward Oʻahu Expedition

During a recent expedition on the Leeward side of Oʻahu, photographer and adventurer Stacy Underwood captured images of sea caves and coastal formations often associated with mermaid lore. These pockets or caves have been identified on O’ahu, Maui, Hawai’i and Moloka’i.
